The dementors scared my younger self which led me to never finish the game. Would love to see it available on GOG with a patch that gives it widescreen support so that everyone can enjoy the game in its full glory.
The fact that we control all 3 of the characters in different parts of the game is super cool. Also it's the most satisfying game to complete 100% cause the card collecting is made way more fun than in previous parts.
Harry potter and the Prisoner of Azkaban is a good RPG with party system.
The scenario is the same in the movies, good but no new scenario.
I play it in during my childhood with friends on gameboy advance and SP. At school, at home, good memory. We share the gameboy for progressing and manage the grind in new game + at 6 players. haha.
The game can go in GOG for the RPG system and a lot replayability.
